IMPROVEMENT IN DEVICES FOR AIDING CUTTING GOODSJON BIAS.

Specification forming part of Letters Patent No. 1311,91 S, dated January 14, 1873.

To all whom it may concern:

Be it known that I, GEORGE MOORE, of Scotch Plains, Union county, New Jersey, have invented a certain Improved Device for Aiding in Cutting Goods on the Bias, of which the following is a specification:

The device presents and properly guides a straight-edged bar or ruler armed with fine teeth or points, which teeth hold the goods against slipping under the knife. The cutting may be done by an ordinary knife held in the hand and slid along the edge of the ruler.

The accompanying drawing forms a part of this specification.

Figure l is a plan view, and Fig. 2 is an edge view, as seen from the oblique side. It is partly in section.

Similarletters of reference indicate like parts in vboth the figures. 4

A and B are bars or arms fixed rigidly at right angles to each other. The bar A may be of the same thickness as the other parts of -the device so as to lie level, or may be made so much thicker that it will bear against the edge of the table or cutting-board, on which, it will be understood, the material to be cutis tombe laid or stretched. C is a diagonal bar, firmly fixed, forming a permanent part of the device, and d d are fine teeth set therein, so aslto protrude their points on the under face. The lower bar A is preferably graduated into inches or other convenient units, measured at right angles to the bar C and produced parallel thereto. The outer edge of' the diagonal bay-r O is faced with brass or with steel, which is thickly studded with the teeth d on its lower edge.

The device is operated with the left hand, While the right hand of the operator grasps a smooth-bladed knife. The device, being placed in position with its lower bar A parallel to the edge of the material to be cut, or, in case the thicker arm is used, bearing against the edge of the table or cutting-board, is pressed down firmly upon the material so that the points or teeth dd enter and take hold of it. The knife is then slid along the outer edge of the bar U. The

device is now lifted, moved along the proper distance, and, being again pressed down, the knife is again operated.

A little practice enables an Opera-tor of ordinary skillV to cut With great uniformity and rapidity. I

The points d d perform a highly useful fnnc wrinkling. Muslin or other fabrics may be laid or stretched in several thicknesses, so that each movement of the knife cuts off' not only one bias piece, but six or other greater or less number.

The main teeth or points d may be either xed or adjustable. The points d are extenscrew-threads, and adapted to be very easily set to project the variable extents. It is well to adjust the extent to which the points d project beyond the face of the device according ing the frame A B C provided With the points d d', and having the bar A adapted to serve as a guide for placing it in position, as herein specified. f

In testimony whereof I have hereunto set my hand this 24th day of September, 1872, in the presence of two subscribing witnnqqnq.
